Space travel is a funny thing. It's the only form of transportation where it is considered perfectly acceptable to throw away your vehicle after every flight. That's a big part of the reason it's so expensive. Imagine having to build a new jumb

SpaceX will attempt the precision landing of a Falcon 9 first stage for the first time, on a custom-built ocean platform known as the autonomous spaceport drone ship. The odds of success are not great--perhaps 50% at best.

Evidence of life on Mars could have been found by Nasa's Curiosity Rover. Mysterious spikes of methane that cannot easily be explained by geology or other theories have been found by an instrument on the robot, which landed

Private spaceflight company SpaceX has been testing reusable rockets to lower the cost of space missions, and over the next two months, the company will attempt the landing of Falcon 9 rockets on a drone spaceport. The landings are schedule for this

There's nothing odd about volcanoes on the Moon, per se. Much of the Moon's ancient surface is covered with hardened lava. The main features of the "Man in the Moon," in fact, are old basaltic flows deposited billions of years ago when the Moon
